AGENDA
One of our current development area’s is with Network Function Virtualisation (NFV),
and how we can integrate hybrid virtual and physical network infrastructure.
1. Why NFV connectivity testing and not straight into SDN and orchestration /
automation
1. NFV and ETSI
1. What are we doing at Alternative:
1. Continual connectivity testing within hybrid environments (VXLAN / EVPN)
2. Virtual Route Reflector / Virtual Routing deployment as virtual host
3. SDN – move NFV connectivity into Openblock (service chaining)
Why NFV connectivity testing and not straight into SDN
- Network function virtualisation can be tested and deployed today without
SDN orchestration tools
- Understand ease of deployment of virtual network function and packet flow
- Look at hybrid and virtual network environments in context of NOC operator / or user
- Core network integration with virtual network elements , VXLAN, MPLS , EVPN
- Once the virtual and physical network connectivity is understood, we will be in a
better position to understand SDN overlay and orchestrated deployment of virtual
network elements.
- Did not want to be just another voice in the room talking about the same SDN
controller concepts.

Network Function Virtualisation and ETSI
“…Leverage standard IT
virtualization technology to
consolidate many network
equipment types onto industry
standard high volume servers,
switches and storage that can
be located in DCs, Network
Nodes and in the end-user
premises.”*
Network Function Virtualisation and ETSI
Test from ETSI use cases based on current user requirement
Virtual CPE – Hybrid virtual and physical network infrastructure
Nothing new, but confirming potential demarcation point
for network and system engineering
Network Function Virtualisation and ETSI
Were next – further testing: OpenBlock - Contrail / SDN POD
Junos Space: Network Director, Security Director
Virtual Director, Service Activation Director
Service Management Systems
OpenStack,
CloudStack
Virtual Machine Management System
Continual Testing
In Summary
- NFV tested, proven, and moving into production now
- vCPE , seen as potential to drop CPE CAPEX and drive new revenue generation
- Hybrid virtual and physical networks are more likely to be deployed using available
tools today.
- No need to wait for production proven SDN orchestration and self care portals
to deploy virtual network functionality such as vCPE.
- 80% of the Service Providers surveyed will deploy Virtual CPE by 2016 but 52%
will deploy in 2014 / 2015 (Surveyed Service Providers representing 51% of
worldwide telecom operators)
